Our ranking pulls from public business listings and weighs review rating and review count, with a modest boost for businesses that show a working website and phone number. We check each business's homepage to confirm alarm and security installation is genuinely what they do, so plumbers or general handymen don't creep onto the page. Permanently closed listings get stripped out automatically. Businesses carrying a Trust Verified badge have gone through our full verification covering trade qualifications, public liability insurance, trading history, customer review history and registered company details, see our How We Verify page for the complete list. Any business without that badge hasn't been independently checked by us, so do your own homework before booking.
